CANFORD LEVEL LIMITED HEADSETS

Canford has considerable experience in the design of headphone limiters and their use in the operational environment. Whilst virtually any headphone or headset can have a limiter fitted, using one of the seven types of standard multipurpose limiter circuits, this usually has to be in an in-line housing. By designing type-specific circuits for individual ear loudspeakers, these can be made small enough and appropriately shaped to enable them to be built into the earcup housing. Adding a limiter circuit to a headphone alters the input impedance.

Notes

1) The quoted limit level of 93dBA, 88dBA and 85dBA is for measurement using dummy head (or mannequin) systems. For measurements using flat plate calibrators the level will differ. Health and Safety authorities are more inclined to use the dummy head type measurement.
